Abstract
In order to make any voltage imbalance between the winding circuits of each phase small and to simplify the edge structure of the armature winding, in a rotating electric machine of four poles, having slots of 9n (1≦n≦7) pieces provided for the stator core with a double-layer winding per each slot, and an armature winding of three-phase star connection being constituted with three winding circuits connected in parallel in each phase, two of the four poles of each phase are constituted with only one of the three winding circuits.
